BATTERY GABLE GONNECTION.

Application led'lfay 7, 1926. Serial No. 107,395.

My invention relates to battery and cabler connections, and has for its general object the maintenance of apermanent reliable contact between these two elements.

t Detail objects of my invention are to provide a connection which can be com leted or separated easily, which will be aapted for cylindrical or tapered battery poles,

' which will include meansV for preventing tu sulphating of the normally exposed metallicparts, and which will e economical to manufacture.

ln the accompanying drawings illustratinomy invention Figure l is a front elevation completely assembled.

section taken. on

`Figure 5 shows my device applied to a battery terminal pole having a taper.

Figure t illustrates a modification of a detail of my invention.

Figure 7 is an isometric view of my preterred housing device.

ln `the drawings, the battery case is indicated at l and one of the terminal poles is indicated at 2, the same being threaded at its lower portion for a nut 3 which clamps the pole tightly against the casing l of the battery, there being a gasket 4 and a bushing 5 beneath nut 3 whereby the interior of the battery is .sealed against loss of electrolyte or escape of hydrogen around the pole 2.

The pole contacting element of my combination is preferably formed of a pair of arms 6 and 7 having a pivotal connection at one end ofv a curved portion of each arm. A simpleform of such connection is clearly illustrated in Fi ure At and comprises a projecting lug 8 ormed on eachof the arms, and a corresponding recess is provided on the adjacent arm. The opposite ends of the arms "are preferably thickened and provided with openings for receiving the end ofa cable 9 covered with Ithe usual insulation 10 and having a tapered shouldered portion 11 and a cylindrical exteriorlyv threadedl end portion 12. The opening in arm 6 is tapered so as to lit the tadll tions @being large enough to of my device and the opening permit the same without any in- `pered portion of the cable 1n arm 7 is large enough to to be moved toward arm 6 terference from the cable. A nut 13 is screwed onto cable portion l2 and serves to clamp the two .arms tightly about the batter pole 2. v

he particular clamp shown is adapted to tit a cylindrical pole as indicated at 2 or to equally well fit a tapered pole as indicated at lll in Figure 5, the recesses for projecpermit the two arms to tilt relatively to each other in a vertical plane as well as in a horizontal plane. In Figure 5 I illustrate to an exaggerated extent such tilting of the clamping members which permits them to fit a tapered battery pole as closely as a cylindrical post.

y To exclude air from the pole 2, clamp arms and uninsulated portions of the cable7 I provide a two-part housing consisting of pan-shaped elements l5 and 16, preferably aving vertical meeting edges whereby the two elements may? be applied to -and removed from the battery arms without necessarily disassembling the latter. I `indicate projecting lu s 17 on member 16 each entering a suitaole recess in member l5 and serving to position the two members relatively to each other. l show ins i8 passing throu h lugs 1'? Aand the adjacent wall portions o' the lug receivpole and clamping i lng recesses for maintaining assembly of the housing elements 16 and 17. Suitablepins 27 may be provided on one of the elements and received in suitable recesses in the other element to assist in positioning the elements.

lill

I- also showv an element holding strap 19,

preferably formed of spring material and U-sha` ed to t over three sides of the complete ousing. VThe ends flanged inwardly engage the bottom of the housing, and the bottom of the housing is preferably grooved or notched at 21 to more securely hold 'the lianges 20. y

The housing elements may be made of fiber, wood, or other non-conducting material, andthe housingelementsare filled with cup grease, petroleum jelly, o r similar material before being a lied. to the terminal members. Surplus iiingmaterial may be extruded through the openings 22' and wipedl oil.

of the strap are at 20 and are adapted to In/Eigurei/I illustrate a modification of /Hfiy/ invention in which the housing is split horizontally and the two parts are held together by a strap 23 extending about three sides of the upper housing element 24 and engaging opposite sides ofthe lower housing element 25 with both of the inturned flanges lof its ends gripping the bottom ofi-the lower housingelement.

The removal of the clamp after 4aY long undisturbed period of application is ren- -dered easy by my invention. When the clamp nut 13 is loosened the two clamp parts are easily separated and may slipped oi of the battery post without dificulty, thus avoiding the loosening or injury of the ost and the plate to which it is attached as is often done with the ordinary connection in which the bod must be bent, bypryingthe jaws apart, before its grip on the post will be relieved. j Y

The terminal clamp elements illustrated are se arately described and claimed in my copen ing application Serial No. 150,898, filed November 26, 1926, as a division hereof.

With my device, the objectionable sulphating of the battery and cable terminals may be. prevented and the nuisance of replacing the cable or its Vclamp or nut at` intervals is eliminated. v Obviously details of my device may be .changed without de 'rting from the' irit of'my invention, an I contemplate e exclusive uuse of such modifi? cations of my invention as fall within the scolpe of my claims.

' claim:

1. In a battery terminal connection housing, Van air excluding body for the battery po e and cable clamp comprising a pair of ali-like members having vertical meeting aces whereby said members may bc applied to and removed from the pole and cable clamp without disconnecting the cable from the battery terminal, there being a laterally projecting lug on one of' said faces and a corresponding Von the other of said faces, andfa pinpassing through said lug 'and 'the adjacent walls of said recess for vholding said members together.

' 2. In 'combination a` battery post, a cable clamp secured thereto, and a housing for said post and clamp, said housing comprising a pair of an-shaped members with their concave 'des `:facing each other and meeting in a line extending longitudinally of the post to which the housing is applied, and means holding'said members together `comprising a strap of sprin material en-V ging three sidesof the housing and having igt;y edges iianged 'inwardly and seated in recesses in the portions of said members formingthefourth side of the housing.
